An upper concave portion 21 is formed just above the lower concave portion 20 on the upper surface of the uppermost square bar 7. A plurality of pores 22 are formed along the vertical direction between the corresponding upper and lower concave portions 20 and 21 in each square bar 7, and the central axes of the respective pores 22 coincide with each other. Further, a communication hole 23 communicating with each of the small holes 22 is formed in the engagement through hole 9, and an axis of each of the communication holes 23 coincides with an axis of each of the small holes 22. A screw rod 24 is inserted into each of the holes 22 and 23, and both upper and lower ends of the screw rod 24 protrude from the inner deep surfaces of the upper and lower concave portions 20 and 21. Then, washers 25a,
When the double nuts 26a and 26b are tightened through the 25b, the square members 7 are brought into surface contact with each other so that no gap is provided between them. The screw rod 24 and the double nuts 26a, 26b allow the wall body 6
Is formed in a panel shape.

As shown in FIGS. 2 and 5A, a plurality of lower recesses 10 are formed on the lower surface of the base 3 at predetermined intervals in the longitudinal direction of the base 3. An upper concave portion 11 is formed directly above the lower concave portion 10 on the upper surface of the eaves girder 5. A plurality of pores 12a to 12c are formed along the vertical direction between the upper and lower concave portions 10 and 11 corresponding to the base 3 and the eaves girder 5 and each of the square bars 7, and the center of each of the pores 12a to 12c. The axes are coincident. Furthermore,
A communication hole 13 communicating with each of the small holes 12a to 12c is formed in the engagement pier 9, and the axis of each communication hole 13 is aligned with each small hole 1a.
It coincides with the axis of 2a to 12c. Each hole 12a-12
A threaded rod 14 is inserted through c and 13, and both upper and lower ends of the threaded rod 14 project from the inner deep surfaces of the upper and lower recesses 10 and 11. 6 and 7, the double nuts 16a and 16b are fastened to the upper and lower ends of the screw rod 14 via washers 15a and 15b, so that the lower end edge of the wall main body 6 is secured to the base 3. On the other hand, the upper end edge of the wall main body 6 is attached to the eaves girder 5.

As shown in FIGS. 3 and 4, side surfaces of the column 4 corresponding to both sides of the wall main body 6 are provided with engaging grooves 17.
Are formed along the longitudinal direction of the pillar 4. Also, a pair of stepped portions 1 are provided at both ends of each square bar 7 in the wall body 6.
8 are formed respectively. An engagement projection 19 is formed by the two stepped portions 18 on the longitudinal extension of the upper and lower locking grooves 8a, 8b at both ends of each square bar 7 respectively. The distal end surfaces of the two engaging projections 19 are flush with both end surfaces of the engaging pier 9. Then, the engaging projection 19 and the engaging pier 9
Are engaged in the engagement grooves 17 so that both sides of the same wall main body 6 are attached to the adjacent columns 4.

Next, the operation of the wall structure in the wooden building constructed as described above will be described. First, base 3
The panel-shaped wall main body 6 is assembled to the pillar 4 built in the above.
That is, with the wall main body 6 suspended and supported by a crane or the like, both ends of the engaging through hole 9 and the engaging projection 19 of the wall main body 6 are fitted into the engaging groove 17 of the column 4. Next, the eaves girder 5 is assembled to the pillar 4 and the wall main body 6. That is, both ends of the lower locking groove 8b of the eaves girder 5 are assembled to the pillar 4, and the engagement piercing 9 of the eaves spar 5 is engaged with the penetration 9 of the uppermost square bar 7. Then, each pore 12
a through 12c and the communication hole 13 are passed through the screw rod 14, and both ends of the screw rod 14 are projected into the upper and lower recesses 10, 11,
The washers 15a and 15b are inserted into the protruding portions, and the double nuts 16b are screwed. Then, the double nuts 16a and 16b are tightened.

Next, effects that can be found from the present embodiment will be described below. (1) The wall main body 6 is composed of a plurality of square members 7, and the screw bars 14 are inserted through the respective square members 7, and the double nuts 16 a and 16 b are tightened at both upper and lower ends of the screw bars 14, so that the respective square members 7 do not separate. I did it. Therefore, unlike the prior art, there is no need for a step of applying plaster, mortar, or the like. Therefore, since the wall main body 6 can be quickly manufactured, the construction period can be shortened.

(2) The wall body 6 is composed of a plurality of square members 7 arranged side by side without any gap, and the respective square members 7 are in surface contact with each other.
Each other is stable. Therefore, the wall main body 6 can be easily manufactured.

(3) Engagement piercings 9 are provided between the adjacent square members 7, between the lowermost square member 7 and the base 3, or between the uppermost square member 7 and the eaves girder 5. . Therefore, even if each bar 7, eaves girder 5, and base 3 shrink due to the passage of time due to the drying, even between the adjacent bar members 7, between the bar 7 and the base 3, or between the bar members 7, It is possible to prevent wind, moisture, and the like from entering between 7 and the eaves girder 5.

(4) Since it is not necessary to use a heat insulating material or the like on the inner wall surface of the wall body 6, when the wooden building 1 is demolished,
No negative impact on the environment. When the wooden building 1 is demolished, the wall body 6 is left in
Since it is only necessary to remove the wooden building 1 from the beams 5, it is possible to reuse the removed wall main body 6 as it is when rebuilding the demolished wooden building 1. Therefore, since it is not necessary to use new wood, an environmentally friendly wooden building 1 can be provided.

(5) Since the wall main body 6 is formed into a panel with a plurality of square members 7, in order to disassemble the wooden building 1, the wall main body 6 may be removed without being disassembled into the respective square members 7. Therefore, when newly constructing the wooden building 1, the wall body 6 can be reused as a second-hand article.

The above embodiment may be configured as follows. (1) In the above embodiment, the present invention is embodied as a one-story building, but it can be embodied as a two-story or more wooden building.

(2) In the above embodiment, the square members 7 are stacked in the vertical direction. However, it is also possible to arrange the square members 7 side by side in the left-right direction. (3) In the above-described embodiment, the square member 7 is used as the wall constituting member. However, other shapes such as a log and a triangular prism can be used.

(4) In the above-described embodiment, the engaging holes 9 are engaged with the upper and lower locking grooves 8a and 8b of each square bar 7, the upper locking groove 8a of the base 3, and the lower locking groove 8b of the eaves girder 5. However, the engaging piers 9 may be omitted, and ridges corresponding to the engaging piers 9 may be formed on the upper and lower surfaces of each square bar 7 by cutting. With this configuration, it is possible to omit the operation of engaging the engaging pier 9 with each of the square members 7, the base 3, and the eaves girder 5. Further, a dowel hole may be provided instead of the upper and lower locking grooves 8a and 8b, and a dowel which can be engaged with the dowel hole may be protrudingly provided at the engagement hole 9.

[0025]

According to the first aspect of the present invention, since the construction can be simplified, the construction cost can be reduced.

According to the invention described in claim 2, according to claim 1
In addition to the effects of the invention described in (1), the wall body can be easily manufactured. According to the invention set forth in claim 3, claim 2 is provided.
In addition to the effects of the invention described in the above, even if each wall component shrinks due to drying or the like and the space between the respective wall components expands, since the engaging member is sandwiched between the respective wall components, the wooden building It is possible to prevent wind, moisture, and the like from entering the room of the object.
